Hang around enough World Cups and it becomes easier to see there is a rhythm and energy to them.
The ultimate winner often goes through the pool rounds incognito. Certainly there have been finalists - France last time, England in 2007 and France again in 1999 - who have been total basket cases in making it to the last eight. That's how it goes, though - there are two distinct phases and while it's always reassuring to see a side play cohesive, energised, organised rugby on the way through, it matters not a jot if they don't.
The pool rounds are about one thing - making it out. Look at South Africa, a subject of global humiliation in their opening game and now an ominous looking beast. It's like the Japan loss didn't happen and it's a good bet that in a couple of weeks, the angst that has developed following two scrappy wins for the All Blacks against Namibia and Georgia will also be long forgotten.
It hasn't been part of the masterplan for the All Blacks to be so off with their skill execution. They didn't set out to drop the ball as much as they did against Georgia or become as obviously frustrated as they did against Namibia.
